Abstract: 1,161,138. Grinding. J. C. FISK. 6 Oct., 1967, No. 45824/67. Heading B3D. A grinding-gauge comprises a hollow head portion for a dial indicator 40, a tubular extension 46, caliper means 260 at the lower end of the tubular extension for engaging a workpiece 30, and a plunger 34, 128 which contacts the workpiece and operates the dial indicator plunger 122 through a lever mechanism 126. A bracket 174 fixed to the head carries a pivot pin 134 for first and second double-ended levers 156, 226. The first lever 156 carries a pin 132 at one end for connection to the plunger and a pair of arms at the other end for contacting the underside of a plate 198 which may be adjusted in height by a screw 194 to limit the travel of the plunger 34, 128. The second lever 226 carries a lug 234 at one end for contacting the underside of the pin 132 and a cross-plate 232 at the other end for contacting the dial indicator plunger 122, the spring-pressure of the indicator serving to press the lever into engagement with the pin. The plunger 34, 128 is urged towards the workpiece by a spring 206 which is spirally wound in the fixed bracket 174 on a tensioning hub 214. Overtravel of the plunger 34, 128 will free the second lever 226 from contact with both the pin 132 and the dial indicator plunger 122. The dial indicator may be fixed in position by a rack-and-pinion 123, 125 and the means 260 may be removed by loosening a screw 280. Water may be sprayed on to the workpiece and grinding wheel by a nozzle 36, Fig. 1 (not shown). In a modification. Figs. 14 and 15 (not shown), only one lever (312) is employed, one end (320) engaging under the dial indicator plunger (122) and the opposite end engaging the plunger (34) through a pin connection (336); in this embodiment the spring (344) acts through a member (342) to tension the lever.

Filed: 1971-10-12
Abstract: 1346216 Recursive filter INTERNATIONAL BUSINESS MACHINES CORP 12 Oct 1971 [29 Oct 1970] 47338/71 Heading H3U A recursive filter comprises two series of delay sections, one having one end connected to receive delta-modulated signals and the other having one end at which the filtered signals appear, the sum of the signals appearing at the other end and taps between sections of one series being subtracted from the sum of signals from the other end and taps of the other series, means being connected to detect the sign of the value of the result of the subtraction and passing a signal representative of this result to the one end at which the filtered signals appear. As shown, one series comprises delays T1, T2, the other delays T3, T4 the signals from which are subtracted at the junction of resistors R1 and R4. The comparator C detects the sign at the output of integrator S4 and passes this via a switch B to the output terminal S to which the other series T3, T4 is connected. A digital equivalent uses a read-only memory ROM (Fig. 5, not shown) to generate the weighted values instead of resistors R1-R6 and these values are subtracted algebraically in an accumulator which produces the sign of the output. Two read only memories (ROM1, ROM2, Fig. 6, not shown) may be used to address an adder which generates the weighted values. A multiplexed filter, in which the filtering response is changed for each different signal applied is shown in Fig. 7. Signals E1-E8 are sequentially connected to the filter by gates A1-A8 and OR gate OR and the input register under control of clock signals H1, H2. The selected signal is fed via delays T<SP>1</SP>1 T<SP>1</SP>2 to memory ROM 1 to address adder ADD. The memory ROM 1 has its addressing output controlled by the selected signal and DECODER as is the control of the accumulator ACC. The sign S is fed via delay stages T<SP>1</SP>3, T<SP>1</SP>4 to ROM 2 and into the accumulator ACC. Gates A<SP>1</SP> 1 -A<SP>1</SP> 8  are controlled in sychronization with gates A1-A8. The accumulator may be an eight stage shift-register (Fig. 8, not shown) which shifts an n bit number each shift pulse, this number being the accumulation of the sign S produced previously. The read only memories can be replaced by any suitable memory.

Abstract: 1413971 Ignition systems; timing ignition FOURNITURES INTERNATIONALES DE MATERIELS ELECTRONIQUES 13 Oct 1972 [14 Oct 1971] 47391/72 Heading F1B An ignition system for an internal combustion engine having a plurality of sparking plugs P includes sensing means T for providing a train of control pulses having a repetition rate proportional to engine speed, circuit means F responsive to the control pulses for providing a corresponding train of rectangular pulses of predetermined width, integrating means Zl, K1, responsive to the pulses of predetermined width for providing a D.C. voltage which varies as a function of the repetition rate of pulses applied thereto and amplifying means A2, A3 responsive to the D.C. voltage and to the control pulses and having a resistance element R2, R3, and a capacitance element C2, C3 in series combination for providing a time constant circuit. In use the output of the amplifying means is in the form of a train of pulses corresponding to the control pulses but with each pulse having a sloping portion determined by the values of the resistance and capacitance elements and the D.C. voltage and threshold trigger means A4, A5 responsive to the output of the amplifying means and being arranged to generate ignition spark delay control pulses which are thus delayed from the control pulses by a time interval which is inversely related to the engine speed. A power circuit Fig.1 (not shown) is responsive to the ignition spark delay control pulses for providing high voltage pulses adapted to operate the spark plugs. When the engine rotates at a speed lower than a predetermined limit N1 the control pulses I are sufficiently spaced to cause the voltage available at the output of the amplifier Al to remain fixed by the divider bridge P'4 P"4 to its maximum value V1. The pulses provided by the amplifiers A4, A5 provide a delay which nullifies the ignition advance. Between the speed N1 and N3 the ignition delay # decreases from its initial maximum value # max, the slope of this part of the characteristic being determined by the time constant C3, R3 of the amplifier A3. Above the speed N3 the ignition delay decreases at a rate determined by the time constant C2, R2. From a certain speed N4 the height of the pulses I 2  I 3  exceeds the threshold voltage V s  of the amplifiers A4, A5 so that the delay # is cancelled and the ignition advance remains fixed at its maximum value. An alternative embodiment of the invention is described with reference to Figs.2 and 3 (not shown). The sensing means T is constituted by a photo transistor D' and a further transistor D". The photo transistor D is illuminated periodically and is associated with a perforated disc driven by the engine. Divisional Specifications 1413973 and 1413974 are referred to.
